Joe H, thanks for the good tips. I will measure as you rec.
Truckernix / Yes, I thought pistons were newer as well. Like I said, rings seem new too. As for removing a ridge, not sure what you mean here? To get piston out, I removed pushrod and pushed it out thru the top, piston first. Bad? Is there something different I should do before removing other 5?
Yes, there is rust, but I am going to blast this thing this weekend w/power washer. I will post pics afterwards to update.
I removed the camshaft tonight and stood it upright as to not lay it flat (read that somewhere). All I did was wipe it with a paper towel. Do you all still agree this is NG. Or some cleanup might be ok? Here the pictures. Also sanded oil pan and stripped of all oil residue. Primed and painted with high heat paints.
I had to feel like I was progressing!
HERE ARE THE CAM PICTURES
